Title: Stylus pressure impressing circuit for reproducing stylus
Inventor: KAGAMIBASHI SHUNJI
IPC: G11B21/20
Filed: 1985-09-09
Abstract: PURPOSE:To decrease the damage of a disk by increasing gradually an abutting pressure between a reproducing stylus and the disk at the time of starting the reproduction, holding once with the abutting pressure lower than the abutting pressure at the time of reproduction usually, and shifting to the abutting pressure in a short time after the fixed time has passed. CONSTITUTION:The abutting pressure between the reproducing stylus and the disk at the time of starting the reproduction is increased gradually, after the reproducing stylus is pressed to the disk, the needle is once held by the abutting pressure lower than the abutting pressure at the time of the usual reproduction and after the fixed time has passed, the stylus is instantaneously shifted to the abutting pressure at the time of the usual reproduction. For example, when the disk with the large surface vibration is reproduced and the reproducing stylus repeats the vibration in the upper and lower directions by the surface vibration of the disk, the reproducing stylus is contacted to the disk by the abutting pressure to the extent in which the disk is not largely damaged, and thereafter, the stylus is shifted to the abutting pressure at the time of the usual reproduction after the fixed time has passed. Thus, the unstable area of the abutting pressure to give the largest damage to the disk can be removed, and at the time of starting the reproduction, the damage given to the disk by the reproducing stylus can be widely decreased.
